In the early part of 1817 the establishment was reduced to eight hundred and sixty seven non-commissioned officers and private soldiers; and in April the regiment marched to the city of Valenciennes, and with the twenty-third, forty-third, fifty-seventh, and ninety-first, formed the garrison of that fortress.
On the 6th of September the Royal Fusiliers were present at the review of the British and Danish contingents by the King of Prussia; on the 9th of that month they were reviewed by Lieutenant-General Lord Hill; and on the 15th of October, by his Grace the Duke of Wellington.

Having passed the winter at Valenciennes, the Seventh were reviewed, in June, near that fortress with the British, Danish, and Saxon contingents, by the Grand Duke Michael of Russia, for whom the regiment furnished a guard of honour. The British troops were subsequently reviewed by Lieutenant-General Lord Hill on the 3rd of September; by the Duke of Wellington in presence of their Royal Highnesses the Duke and Duchess of Kent, on the 10th of that month; and on the 23rd of October by the Emperor of Russia, King of Prussia, Prince of Orange, &c. &c.
Soon after this review the establishment was reduced to seven hundred and forty-six officers and soldiers; and the Army of Occupation being withdrawn from France, the regiment marched to Calais, where it embarked for England, and landed at Dover on the 2nd of November.
After occupying Dover Castle barracks a few days, the regiment marched to Deal, where it embarked for Ireland, and landed on the 26th and 27th of November at the Cove of Cork, from whence it proceeded to Fermoy, and, in December, to Dublin.

The regiment remained at Dublin until August, 1820, and its appearance, discipline, and interior economy were commended at the half-yearly inspections made by Major-Generals White, Buller, and Sir Colquhoun Grant. It subsequently occupied extensive cantonments, the head-quarters being at Londonderry, where it was inspected by Lieutenant-General Sir David Baird, and Major-General Sir Sidney Beckwith, and obtained the approbation of these distinguished officers. In November it embarked at Belfast for Scotland, and landing at Port Patrick, marched from thence to Edinburgh and Glasgow: its appearance and discipline were commended at the half-yearly inspection made by Major-General Sir Thomas Bradford; and in June, 1821, when it was ordered to march to England, this general-officer "expressed his warmest approbation of the uniform good conduct and regularity in quarters, as well as of the high state of discipline in the field and excellent interior economy;" at the same time requesting "Colonel Sir Edward Blakeney to convey these sentiments to the officers, non-commissioned officers, and soldiers."
Leaving Scotland in July, the regiment proceeded to Newcastle-upon-Tyne, Carlisle, Tynemouth, and Sunderland; and in August the establishment was reduced to six hundred and fifty officers and men.
